Features for the CD4521B

  • Reset disables the RC oscillator for low-power standby condition
  • VDD’ and VSS’ pins are brought out from the crystal oscillator to allow use of external resistors for low-power operation
  • Maximum input current of 1 µA at 18 V over full package-temperature range:
    100 nA at 18 V and 25°C
  • Common reset
  • 100% tested for 20-V quiescent current
  • 5, 10 and 15 V parametric ratings
  • Standardized symmetrical output characteristics
  • Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of ’B’ Series CMOS Devices"

Description for the CD4521B

CD4521B consists of an oscillator section and 24 ripple-carry binary counter stages. The oscillator configuration (using IN1) allows design of either RC or crystal oscillator circuits. IN1 should be tied either HIGH or LOW when not in use. A HIGH on the RESET causes the counter to go to the all-0’s state and disables the oscillator. The count is advanced on the negative transition of IN1 (and IN2). A time-saving test mode is described in the Functional Test Sequence Table and in Fig. 6.

The CD4521B types are supplied in 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
